Drilless Tub Doors?

I swear I saw one at Lowe's - a set of tub doors that could be installed without having to drill into the walls. When I went back last night, I couldn't find them and the clerk was clueless.

I temporarily live in an apartment. I'd like to put in the doors because my kids LOVE to take baths but always end up making a huge mess. I know the complex would frown on my drilling into their walls/fiberglass tub set-up to install.

I believe Keystone makes this. Basically, the top and bottom rails were spring-loaded to fit. However, I don't remember if this was just to avoid having to cut the rails. I don't know if the springloaded rails were sufficient to keep the side rails vertical/
